What is Azipod propulsion?
What is Azipod propulsion?
Azipod® propulsion is a gearless steerable propulsion system where the electric drive motor is housed in a submerged pod outside the ship hull.
Do cargo ships have Azipods?
Today, ABB’s Azipod propulsion systems are used on a wide range of vessels such as cruise ships, icebreakers, ice-going cargo vessels and offshore accommodation ships.
Do all cruise ships have Azipods?
Most cruise ships have two pods. However, Oasis of the Seas and Allure of the Seas have three pods. Several ships have a combination of azimuthing pods and pods that do not turn (sometimes called “fixipods”) that are used to provide forward and backwards propulsion. Not all cruise ships use pods.
Why do Azipods pull?
The propeller is on the front of the pod and thus pulls the ship through the water rather than pushes it as with a traditional propeller and shaft system. In the traditional system, the propeller is turning in water that has been disturbed by the passage of the ship’s propeller shaft, framings and brackets.
Who invented Azipods?
Azipod is a term coined by contracting the words “azimuth” and “pod.” This refers to the propulsion unit’s ability to move 360 degrees. Azipod technology dates to 1990 when ABB, a Swiss company, first developed it.
How many types of propellers are there?
There are three basic types of an aircraft propeller, each with its own variations – the fixed pitch propeller, constant speed propeller or the ground adjustable propeller.
Who made Titanic propellers?
Harland & Wolff’s
Harland & Wolff’s records show Laurentic (1909), Demosthenes (1911), Titanic (1912), Arlanza (1912), Andes (1913), Ceramic (1913), Katoomba (1913) and Alcantara (1914) all employed a propeller configuration consisting of three propellers which were all three-bladed.
How do diesel electric ships work?
In diesel-electric systems, multiple diesel engines, each driving an electric generator, produce the electric power that energizes the electric motors connected to the propellers as well as other electrical loads on the ship. Depending on electrical demand, not all diesel generators have to be operating at all times.
What are the parts of propeller?
The basic parts of a propeller are the blade, shank, hub, and leading edge. The blade is an arm of the propeller from end to end. Most propellers have two or more of these. The shank is the thickened section of the blade near the hub, which is connected to the propeller shaft.
